What Causes Oil Leakage from the Passat Engine Cylinder Head?
1 Answers
There are several reasons for oil leakage from the Passat engine cylinder head: Oil seal leakage or gasket failure: For issues like oil seal leakage or gasket failure, you can disassemble and replace them, or apply heat-resistant sealant. Currently, there's also a small trick—adding a solute claimed to enhance rubber plasticizer into the engine oil. After normal driving for a period, the oil leakage condition may improve. Excessive engine RPM: Matching vehicle speed with RPM helps reduce engine oil leakage. It's best to keep the engine RPM below 2500rpm. Shifting gears when the RPM exceeds 2000 can not only prevent oil leakage but also reduce engine wear.
